PlayerUnknown's Battlegrounds brought battle royale games into the mainstream, but in just a few months, Fortnite has taken over. It's passed PUBG's player count. It's the most-watched game on Twitch, doubling PUBG's viewership. At the beginning of 2018, search interest for Fortnite skyrocketed and hasn't fallen back since.

For those who don't know Fortnite's tumultuous seven-year history, it was initially just a PVE shooter letting four players build constructs and blow up zombies. But when the developers at Epic decided to release a free battle royale game mode to get more players on board, PUBG's developer, Bluehole, voiced concerns about whether Fortnite is nothing more than a brazen rip-off.
